Not to derail here... But I climb in Lasportiva Makalus with no complaints. Granted they were my backpacking boots and were well broken in by the time I started climbing.
I'm not sure which scarpa boot the OP is referring to. But I can say, that scarpa footwear is quality stuff. Lowa garmont, lasportiva, mammut, all make good stuff as well.
The most comfortable pair of hiking/mountain style boots out there are Salewa, hands down. The Salewa Rapace is definitely worth a look and will probably be my next pair. I bought a pair of Salewa shoes over the summer and they are easily the best shoes I've ever owned. Period.
