As always, it depends…!
If you use slotted drivers a lot, then you will know that some screw slots are Imperial sized, others are metric.
If you’re working on Imperial sized screws, you need Imperial sized drivers to avoid damage. The question I would ask is “what’s best?”
Having been using such drivers for several decades, I don’t think there are anything better than the older style Snap On “hard handles”
The blades are superbly forged, superbly finished, and there isn’t a better handle material for greasy environments. I know aircraft engineers who have had the same drivers for 20 years plus, and wouldn’t use different.
Are the Snap On worth it? Well, they were to me a few years back, when I bought the ones I have. Would I buy them now? Perhaps not. Would I pay the same for the “Instinct” handles? No, they’re a cheaper, low density, material and the drivers should be cheaper.
If I primarily needed Philips drivers, then the equation changes again, and if I needed metric slotted then you are definitely better off with something different.
I’m not a huge fan of soft grips, they’re not suited to automotive use, but PB Swiss, Vessel, Felo, Heyco, Facom, KTC and a dozen others all make perfectly good hard handle drivers at a fraction of the price of Snap On.
I think the Megadora’s are comparable (ish) with Snap On Instinct. Not much to choose between the handles, the slotted tips are metric (which could be good or bad), the “Jawsfit” Phillips (and Pozidriv) tips fit better than Snap On, but long term I think the Snap On blades are better.
If you compare the “Powergrip” (different blade and handle) then I think they are comparable to (or better than) the Snap On Instinct - for a fraction of the price, provided you don’t mind metric tips.
