I have the Talos and the McNees PM 2.5 - I actually picked up the McNees because some of the design points reminded me of the Talos. lol
Here's my honest thoughts on the two, especially if you're considering dropping the Talos.
The McNees is a great looking knife with decent ergos. It's shorter than the Talos, and a bit more scrunched on the grip.
McNees is on bearings, and the Talos is PB washers. I much prefer washers on a thumb-stud knife, and the Talos is smooth as glass on them.
I...
hate...the McNees jimping on the spine. It's sharp as hell - it makes my SHF feel like velvet. lol The lockbar is also stiffer than the Talos, and combined with the thinned edge, it's just not as comfortable and smooth as the Talos.
The working finish on the McNees blade looks like concrete. I'm not a huge fan. The grip on mine is absolutely
gorgeous though. I love the swerve pattern, and it provides a really solid grip.
The detent on my McNees was too stiff. I had to adjust the lockbar to get it where I wanted it (no biggie - I've done this on a few LGs as well).
Summary:
I listed a lot of negatives, but the McNees is really a great knife (I'm just being picky for the sake of comparison)...I have no plans of ever getting rid of mine. The bronze / blue swerve grip pattern on mine is just a knockout. If I had to pick between the two, I would hands-down take the Talos. It's better in pretty much every category that matters to me.
