Yes, I like the lesser known #22 as well.

All of Mozart's piano concertos are excellent, as I see it.

When it comes to favorite performers, I think it depends on works. Eg, I like Bachkaus's rendition of #27. One performer I'm particulary fond of is Clara Haskel. Uchida is good, but I perfer Haskel as her performance is more flowing, more intimate to me.

Thanks for the Brahms links.
I used to like Brahms a lot, but my interest in him seems to have diminished quite a bit. However, I'm still quite fond of his piano trios by Rubinstein, Szeryng (violin), and Fournier(cello)
