Used to be recurves were generally faster but could be finicky. Longbows were quieter but shot heavy arrows really well. These days, with string developments and changes in bow designs, the top longbows run pretty much neck in neck with the top recurves for speed. I still think the average longbow is quieter than the average recurve but both can be setup pretty quiet. I probably would also say I prefer the heel down grip of the longbow over a high wristed recurve grip but lower/medium type recurve grips are quite comfortable. This year, for the first time I am shooting a recurve instead of my usual longbow. It's an older Wilson Brothers Black Widow that formerly belonged to my best friend and amazingly I'm shooting better than ever with it.
I guess bottom line, find one you just feel really good about then take the time to really match the right arrows, point weight, brace height etc to get everything flying perfect and either type will get the job done.
Read that last sentence again... Take the time to tune your setup, match the right arrow spine, point weight, shaft length etc etc. Those simple steps will make or break your setup regardless of the type bow you decide to shoot.
