Get the 34. Buy once cry once. The 34 is definitely better than the 32. The difference in target separation alone when scoping fish around cover, and when they are glued to the bottom, is much better. You also do not need a huge battery - just for a single graph and livescope. I have it on my kayak with a 93SV and still have 25 percent of a 35AH battery left after an 8 hour tournament. If you want beautiful clarity - get a 16v battery. I run a powerhouse lithium 16v 100AH battery on my bass boat that is dedicated to just my electronics and the clarity using the 16v is awesome. Not just for scope, but for side scanning as well.
