You will have to judge the feel for yourself. Keep in mind with any of these that there will be a sensitivity adjustment of some type that will modify this a bit.

One thing I like about the Casio keys is that the surface of them is not completely glossy; there's a bit of intentional non-glossiness (it's hard to describe)that helps. I wish my Casio XW-P1 had the same surfacing. It's almost like fake oak, or really old school ivory (playing these keybeds reminds me of the 1800's era upright we had in our basement when I was a kid with wooden surface black keys and real ivory surfaces on the white keys.)

You'll have to judge this for yourself. Here's a pretty glowing review of this specific model from Keyboard magazine: http://www.keyboardmag.com/combo---do-all/1191/casio-privia-pro-px-5s-review/29374 It doesn't shed any light on the tri-sensor action - but this specific site at Casio talks about it a bit, but I don't think it will give you an idea for 'feel'.

Here's the good news, there's tons of value out there. You might be more comfortable with the Roland brand name, you can't go wrong with it, but since this is likely a church budget, you might put overall cost higher on the priority list. One other thing that might not play well, is it's appearance - it doesn't even try to look like a church instrument.
