If happy with the colour temp and gets plenty of use, I agree no point. But if it's going to get shoved in a draw because it's too cold or blue or etc etc. It's a great option to upgrade with a more modern LED keeping the classic HDS form. Pic your flavour and enjoy the light, rather than just storing it. That's me though, the little novatac recently was not too bad in original state. The beam was pure white, no actual tint. But it was not very bright and washed colours out a little. I would not have used it much as I would have simply grabbed a preferable light with a more pleasing beam. This had a 219c 5000k to keep a more pure white, yet colours now are not washed out. Not only more enjoyable (for me as subjective),but it gets used and part of my edc rotation. The lumen bump was a bonus! It's surprisngly bright and more than enough on high for 95% of my uses.
Advatages lower vf, brighter , nicer beam colour temp/tint. Life's too short, might as well just enjoy it to your preferences, if that's standard then even better.....money saved:twothumbs
