BHP - Classic cocked and locked 9 with a Mag' Safety drawback. Some versions don't allow drop free mag's. Mag' safety can be removed (which generally allows mag' to drop free and improves trigger).
CZ-75 - Value, good ergonimics and forgiving platform (another cocked and locked alternative). Agreed that safety placement takes some getting used to. Similar to BHP which inspired it, some versions don't have drop free mag's. A CZ-85 Combat may be the best of the bunch.
Sig P226 - Quality out of the box, but the DA/SA transition takes some practice. Depending on model chosen, price can be far greater than the other two. I find Sig's recover better on follow-ups than other platforms.
Hard to go wrong with any of them. Triggers can be worked. Sig' may have best out of the box...my '99 CZ-75B trigger in SA is every bit as good or better than the SA in my P220ST. My Arcus (BHP Clone) is operationally easier than the CZ-75 and I don't have to deal with DA/SA transition BUT, the out of the box trigger is only so-so (probably going to visit the smithy in the next few months).
I voted CZ-75 because of my experience with two CZ-75's (a CZ-75B and a CZ-75 Transitional).
As has been stated many times, autoloaders are like shoes...see if you can "try them on" and find the one that fits you best.
Good luck!
