I happen to have 5 OD/Distortions. Here they are in order of preference/usefulness plus some comparisons with other pedals.

(1) and (2) are currently in my pedal board.

1) Maxon OD9 (Tubescreamer): The OD pedal I use the most which works best for most things in a band context, even though it's not as impressive as other pedals in isolation. I could get by easily with just this pedal.

2) Angry Charlie v2 (I haven't tried the v3): This is my most recently purchased pedal which I've had for about a year and used for numerous gigs as well. I got it because I wanted something a bit more full on. I compared loads of pedals at Andertons including a Wampler Pinnacle, Suhr Riot, Xotic BB but preferred the Angry Charlie. This pedal sounds impressive in isolation and in a band context, used sparingly for occasional sustaining lead and shred. I think it might become wearing if used too often in a set.

3) Maxon SD9: I got this before my OD9, after Scott Henderson raved about it. But I couldn't get the full-on sound to work for me. I use it on minimum OD and it gives a nice glassy crunch. I'd have this in my pedal board as well, but it won't fit.

4) Boss OS2: I've had this for many years and it's my oldest OD pedal . I only use it with the colour knob hard over on the OD end of the scale. It definitely doesn't sound impressive in isolation, but it works really well in a band context and occupies a nice frequency slot that cuts through without dominating the overall sound too much. A good all rounder. I carry this as a spare.

5) Fulltone OCD v4: This sounds great in isolation. It's my second oldest drive pedal and I remember trying loads at the time. But I've never been able to make it work in a band context, because it's too mid scooped. The important frequencies get lost in the mix and it just ends up sounding thin. So it's my least useful OD/distortion pedal.  I still hang on to it, because it might fit with something I do one day, given that it sounds good in isolation.

In no order.

Goosoniqueworx 7thvn - super amp like, hi gain, yet low noise
Marshall Guv'nor mk1 - still a Marshall in a box
Pro Co RAT - That 90's alt sound
Boss SD-1 - Great all rounder
J Rocket 10 Ton Hammer- Amazing tones, similar to 7thvn, but noisier & powder coating comes off.

Hoochee Mama - now using a juansolo clone but sounds the same - lovely cooking od. 

Klon Centaur - now using a juansolo clone but this is an essential, always on, last in chain, controlled by guitar volume. 

Rodenberg GAS827 - ultimate tube screamer. 

Mooer Cruncher - lovely snarl when I need it. 

Cream Tone - should have kept it but kept getting pushed out by all of the above. 

Honourable mentions (because I like what other people have done with them ):

i liked my Mooer Hustle drive as well just until it decided to go all melty and die.

i find all these very situation dependant though.

The Tim is great at gig volumes and is pretty much all I need on my board going into a clean JCM800.  At quiet home volumes I found it a bit dull and gritty.

The Guv'nor needs a big 'open sounding' amp like a jcm 800 or twin reverb.  It can sound very boxy in a smaller more congested sounding amp.

The Shredmaster is opposite the guvnor really, it gets really bass heavy and boomy into big amps but works best IMO in clean combos with 10 inch speakers. In that situation the excess bass really helps.

although not strictly in this category, I must also mention the Koko Boost and EP Booster for their sheer awesomeness

That's a tricky question, but amongst my favorites:

Subdecay Liquid Sunshine - Low gain make everything sound better pedal
Marshall Shredmaster - Prefer it to the Guvnor for extreme rock hugeness
MXR Super Badass - Awesome versatile distortion
Boss OD3 - Underrated for driving a clean amp
Wampler Velvet - Great fuzz solo hugeness into a clean amp.

Should also give honorable mentions to Thorpy Peacekeeper and Fallout Cloud

My list has always been small, but I've been able to try quite a few new pedals in the last month..

1) JRAD Tim Pierce OD - This is the best OD pedal I've ever owned. Requires you to want your sound from hitting the amp hard. Bit like a Zvex super duper 2 in 1 but more refined and more control. Also an amazing always on pedal
2) Ehx Soul food, It's been on my board for 3 years. Great at pushing and thickening an amp for lead boost
3) Gurus 1959 DD, very new to me, so still in the honeymoon phase. but an all singing, all dancing preamp pedal
4) Zvex super duper 2 in 1
5) JRAD Rocket, sounds really nice if you can dial it in with your amp and guitar, seems to work better with some combinations than others. 

Not really an overdrive, but the Skreddy Lunar module is an awesome fuzz that functions like an OD and would go to place 2.

Customtones Ethos Overdrive: Does the D*mble ODS sound very well but is far more flexible in the range of OD sounds available. The Boost setting, whilst being uncomfortably middly in isolation, ensures that solos punch through a ham-fisted and heavily distorted rhythm guitar.

Wampler Tumnus: My favourite of the Klon clones.

An original 1964 Roger Mayer fuzz. Gorgeous fuzz tone. Now sadly deceased.

J Rocket Blue Note Tour Series: Ridiculously transparent low-gain OD. For those times when you want your pure guitar tone with an edge but no colouring.

Not a pedal but the Digitech 2112 rack-mounted multi-effects unit I used with a Control 1 pedalboard through much of the nineties has excellent valve and solid state ODs/distortions.
