With a Steel framed 1911 I like Chip McCormick PowerMags. The extra power springs ensure that the next round is ready to go every time.
The only place I use the softer sprung Wilsons is aluminum framed pistols. The anti-tilt follower is easier on soft aluminum feedramps. But I'm starting to replace my Wilsons with Checkmate mags.
