I don't have any recent (last was 10+ years ago) experience with the HO snap switches.
I do have very recent experience with the N scale custom line and snap switches, though.
The snap switches are very iffy, and often require more work than they're worth, for reliable operation. (or any operation... at times)
The Custom Line manual turnouts are very decent. Reliable, cheap, drops in the same footprint as the snap switches. (as long as you use the same turnout # such as #5, #6, etc)
The only real drawback is a problem you have with the snap switches, as well. The guard rails are injection molded plastic, and designed to let the wheel flange support the axles. Well... that's not the way prototype switches work, and it makes for a sloppy / unreliable setup in modelling.
So... if you have the money, I would recommend upgrading to a higher quality turnout, such as those listed in previous posts. If not... tinker away, or go with manual throws.
