2A3 is a bit trickier to use but if your speakers are high efficient then the 2A3 will sound a lot better than the 300b.
When using triode tube, smaller(I mean power output) is better(better sounding).
Personally I'm using 245 triode for the mid/high of my bi-amp system. The 245 just blown the 2A3 and 300B(original WE 300B) away.
If you really go for the SE Triode thing, you should get yourself a pair of highest efficient speakers that you can get or build and then you can play with any triode tubes you like.
