OK, if you want a slightly more serious response:
The Bits are nice synths - build quality is good, keyboards are lovely and springy, you get velocity sensitivity, they look nice and sleek, and they have a fairly typical Curtis brassiness (clearly I'm only referring to the bulk of them here, only the very earliest BitOnes had SSM filters). It's nice to have MIDI and splits/layers, and there are good features in the synth engine itself - two LFOs that are fully independently routable to multiple destinations including with velocity sensitivity and mod wheel amount - probably one of the best features of them, IMO.
But then there are the downsides of the Bits - those oscillators are the most static I've ever heard on anything, ever - and so to counteract this, I use some subtle LFO modulation to pitch. This immediately ties up one of the two, leaving the commonly-found single LFO for other duties, so no great killer there - but even so, the possibilities are then reduced and that may be one of the factors in the general ignorance of the Bits. I do think they are very under-rated and under-apppreciated, but the main downfall is the interface - not a single data slider or knob, it's all down to button-pushing. That makes even minor changes a pain in the region of your choice, and going from 0 to 99 is no fun at all. The buttons are not that lovely to push, either. For me, this is the major factor in why I do not use my Bit99 more. I've made some very nice patches, and the thing can sound bloody lovely through a good reverb, but it's just not much fun to program.
There's no PWM via LFO, which is odd - but you do get velocity control of it, which is nice. The One and 01/99 have different modulations for this, so my comments are based on the 99. Also, there are weird phasings going on between the oscs sometimes, that can distort the filter - I think it might have something to do with the way the waves are generated and so tightly locked.
When it sounds good, the Bit is a great bit of kit - but you really need to spend so much time programming it, other synths tend to be more useful.
As for the Obie, well, I've never used one. I get the impression they're going to be more intuitive to program and easier to navigate, and that the oscs will not be so fixed as is.
Comparisons are never going to be based solely on sound - though if you want an opinion based on direct experience, I think they sound quite like the Obie Matrix 6R I had for a while - though the 6R had the benefit of a wider array of modulation, and looser oscs, it shared the slightly painful editing process. I like my Bit, but I'm looking to sell it because, as nice as it is, and as unique as some of its features are, I never use it and the space could be better served by something I will use. If you're looking to buy one, the Bits are a great deal cheaper than any vintage OB-X-type, and I'd recommend trying one to see if you get along with it. That's all.
