Dynamic mikes are supposed to be better for open cockpit and heli flying (i.e. noisy cockpits) but I flew an open cockpit Pitts with both and the electret was better. On DCs the dynamic option (H10-30) is cheaper but I would go for the H10-13.4 as it has a better boom and mike. DCs are very hard-wearing and probably the best you can get for GA, all things considered.
Don't bother with Bose unless you have money running out of your ar5e, they are not worth the money and are utterly sh1te with ANR off.
