That is very personal but may be this help you.
1) If you want to open a reel every time you have to change your settings and dig with your wet fingers in little caps, get the Curado.
2) If you want to comfortable and quickly do it by dialing a tiny wheel from the outside, get the Revo.
Good luck
Hmm... Ive seen these kind of staements on here before, but never really understood them. The way I was taught about a baitcaster and how to use it was to set the brakes ONCE and let them be, and then use the cast control tension knob on the other side to adjust for the conditions if needed (i.e. really windy, lighter weight bait,really heavy bait....etc...)
I guess its just a preference thing, I have had reels with both types of brakes and on the ones with the external brakes I found myself spending more time adjusting them and blaming them for my lack of control. They basically became a crutch that I blamed in place of my real fault of not enough practice.
Needless to say, I now have a curado 100, calais 100, and 3 calcutta 50's and the last time I had the reel open to adjust the brakes was also the first time. It just isnt an issue with me I guess....
To each his own though...its what makes the world go round.
