Get fitted :) If you're buying a new set any good golf store with a good fitter will spend a lot of time with you, let you swing different sets, and fit the one you choose.
That said, I've got the older Titleist 695 CBs, and I really love those clubs, and when I have the money to get fit for a new set whatever Titleist 7XX set that's current then will definitely be at the top of the list of clubs I'll consider. So I'll vote Titelist even though I haven't ever swung the Clevelands you're asking about :)
I'm very sympathetic to the feeling that you don't want an iron that looks like an abstract corporate art sculpture from the back, with a huge oversized face and thick top line, but I'll just throw out there that as a player who's up to an 18 with weekend warrior playing consistency and was a 10 even playing 3-4 times a week, why the insistence on the most blade like irons? I love my CBs but as I've gotten better and have started to have at least some rounds where I'm hitting it consistently and not spraying even the long irons, I've definitely started to notice there are some shots where even with the CBs I can make what feels like a good swing and hit the ball within a tight, good day dispersion cone, but hit the ball a bit off center and end up short (either super long putt with back pin or off the green with front pin). And that's even on days where the full swing game is going great and gives me the opportunity to play in the 70s (though some of those days are in the 70s and some the short game or putter doesn't cooperate and I end up in the 80s anyway). Can't imagine you couldn't use at least a tiny bit more forgiveness than the MBs as a 10-18 player, and you don't have to get art-deco space ship irons to get more forgiveness than those.
