Of course, the Delta Elite is a classic. I recently purchased an EAA Witness Match. Fits my hand well. If the glock fits yours, then it's hard to beat. You can get an aftermarket 6-inch barrel if you ever want to use it as a primary hunting gun and the Glock 20 was built from the ground up as a 10 mm. Some guns were built on smaller caliber platforms and that can cause durability problems. Don't know if the model 20 Gen 4 is out yet or not. The Gen 4s have a slimmer, more contoured grip. Even the 20 SF felt bulky to my hand.
