FR4 is the most widely used PCB material, I have never specified anything in FR3.
FR3 is a paper based product with an epoxy binder rather than the phenolic binder of FR2 and was (is) used fro extremely cheep products.
I would stick with FR4, and wouldn't be suprised if it was cheeper to use, in the UK all the PCB houses I use quote cheeper prices for FR4 as it is the standard product and they hold stock.
