Having wet-shaved with DE and straight razors, I've experienced a wide range of blade types. By way of background, I have average/dry skin with thick, dark growth so I'm a real challenge for most razors!
Until earlier this year, I had been using Derby Green DE blades in Merkur and Gillette razors. I thought they were Ok but in recent years, the Derbys seemed to have decreased their quality control so I moved to Personna Red Packs (Israeli made blades). I also mixed things up with Feathers (way too sharp for me and left me raw) and now the Merkurs.
Of all those blades, the Merkur blades reminded me most of the Derbys - plenty of feedback, not particularly smooth or sharp, generally inoffensive but without the QC problems I'd been experiencing with the Derbys (I could have sworn that the Derby edges weren't straight as I could feel parts of the blade regularly scraping and nicking my neck and they also didn't hold their edge very well).
For the price of the Merkurs, I just couldn't justify them further and have gone back to the Personna Red Pack. The Personna Reds give an amazing, super smooth shaving experience that everyone should try.
As always with these things YMMV.
