I do not like my 1.95 Cinder rear tire. It "mudded up" way too fast, failed to shed the mud quickly, and will be too small for some summer Super D races. I think it will still be a reasonable tire for winter but for summer riding, may not be ideal. I am at a lost for a decent mud-shedding tire with minimal rolling resistance. Maybe this discussion is purely subjective but before I buy a half dozen tires to try what is out there, thought I would see what others have to say.
This is for my hardtail and primarily xc riding.

I'm rolling on some Maxxis Larsen TT 2.0 70a tubed version tires. They seem to shed mud well and the rolling resistance is minimal. The angled knobbies are the deal. Traction in loose stuff on steep grades is not the best due to the close spacing of the knobbies. I'll take the good mud shedding and the low rolling resistance positives over the not so good in loose stuff on steep grades negative....

I've been pretty happy using Kenda Nevegal 2.1's. They work well in most conditions and roll nicely. Price isn't too bad either.

I like the Schwalbe Nobby Nic. A lot.

I don't know what type of mud your are riding in, but I completely disagree that Larsen TTs shed mud well. In my experiences Larsen TTs could be the WORST possible tire for shedding mud.

My nevegals don't shed mud well, but they hook up on hardpack.

No one tire can do it all. I would recommend a set for the winter muck and a set for the dry months. If you have to stay with one for most of your riding the Hutchinson Spider 2.30 is hard to beat.

Schwalbe Alberts tend to do pretty good for me.
