It's no surprise to me that you liked the STI Escort. Both of my carry weapons are from STI. The VIP (double stack) and the Guardian (single stack) I have been very pleased with all four of my STI pistols. All are very smooth and accurate. If you don't go with STI, my next choice would be the Sig. I'm not a Glock fan (good gun, just not fot me) and I've owned a Walther and much prefer STI.
