32, 34, 36 and 38 are all very common. Which is best depends on other considerations, including the size of the outer ring and cassette. I like to keep the steps nearer to 10 teeth, so 24/34/44, or 24/34/44 make more sense to me. If I go to a bigger step, it'll be between the middle and inner as in 24/36/46.
The way I prefer to set up the gearing using a 32 middle would limit me to a 42 outer, which is a bit small for long shallow downhills.
But that's just me. Everybody needs to pick chainring sizes and cassettes suited to how and where they ride, and there is no one best way for everybody.
