At least by me, 1100's are more expensive than 11-87's. I've also heard both can have problems cycling when using light loads (hence the appeal of the SPR453). My wife wants something with a synthetic stock, so that leaves out 1100's too.
I've checked on huntingnet.com and they seem to be well liked. I have the SPR310 over/under, and I really like it, so I know Baikal is capable of building a decent shotgun.
Either way, I will probably end up with an 11-87 eventually.
