Don't quote me on this but I think most blades will have a PTFE (Teflon) coating of some sort, but some have more than others. I think both Voskod and Feather have a PTFE coating.
I've not used Voskod at all, and everyone's face is different, so I'm not sure how good my recommendations will be, but for me personally nothing beats Tiger Platinum blades made in Czechia. They are made by the same company who used to make the Astra blades for Gillette before they moved production to Russia. Here in the UK I only ever see them in specialist shaving shops, but they're easily obtainable online. My second favourite are the German made Personna Platinum blades.
I know you said you didn't want to experiment, but I do think that's the only way you'll find "your blades". Even though I'm perfectly happy with Tiger and Personna I've still got a stash of 5-10 blade packs of various brands that I haven't tried yet; every now and then when I'm feeling adventurous I'll give one of them a try and see if it's an improvement on what I'm currently using. I know it's cheaper to buy in bulk but I'd never buy a 100 pack of a blade I've never tried before.
