I have both round and LP reels ---- Love them both. Both equally performing well.
Personally, it is more of a "weight" issue than performance. I prefer using my lighter LP reels on days where I would be casting more often and would be moving around often to different fishing spots especially when I am shore-line fishing. And I would use my heavier round reels more often when I am on a boat.
My advice is to have both. BTW, go for the shimano E series (citica or curado). I like them better than my Revo Sx. Based on my experience, centrifugal brakes seem to perform better than the magnetic ones. ...... (just my 2 cents.)
Good Bites to all and happy Thanksgiving.
