There are some off the shelf 19t's that are slower than others. There are some tuned 19t that are super quick. It really depends on what you buy. $50 on a brushed 19t will get you a better motor than $19 on a brushed 19t.
If you plan on racing in a specific class, your best bet is to see what is allowed in the 19t class at the track that you go to, and buy that.
If your just buying one to have fun with and want a BL that is most similar to at 19t, and racing in a specific class does not matter to you, I would say 10.5.
I went from 19t to a 10.5 and feel they are about the same in the power / speed department, though with a lipo I would give the 10.5 a very slight advantage.
You will also notice much longer run times with the BL.
