I've been DE shaving for two months, my brush is a Vulfix 2235 Superbadger. I get very good results with soaps and creams although I understand that it's a soft brush and perhaps not ideal for soaps. I have nothing to compare it to so I don't have much to comment. I do notice that when I'm doing a scrubbing motion, it doesn't feel like much (probably because it's so soft / floppy).
My next brush should probably be good for soaps and creams. If I love it for soaps but not creams I can always use the Vulfix for creams. On the other hand, if I love it for both, I'll probably sell the Vulfix.
The top contender is probably a Shavemac Silvertip 177. Another strong contender is a small or medium Rooney Silvertip. While I can spend more than $100 if I "must" I'd prefer keeping it around that mark.
Any suggestions? (I realize there are a ton of options here).
