Revo. The drag on the Revos is awesome and the new chronarch is just a repackaged old curado. If you were saying SX vs Chronarch, then Chronarch, but the STX is the best reel at its price point.
And, to boot, this place is selling them for $154
I was an ALL SHIMANO kind of guy before I got my Revo. Love it. I've caught some steelies, striper and lingcod on it that all ripped out drag for days. It's really a great reel.
That being said - get one of each
