For DE, I use Personna reds, astras and super plat+ israelis.
No particular order, depends on the razor, some work better than others.
I've tried about 20 different blade brands, some better and/or more expensive.
The three chosen are because they do the job, are cheap and readily available, so bought 100 of each.
Still have packs of 5 or 10 of many other blade brands I bought in sample packs or in small quantities or traded on forums etc. I just leave in the cupboard mainly these days, I'm not bothered to start a blade I've forgotten about or work out the best razor and angle to use with it again.
But the 100 each of red packs, astras and israeilis is pretty much a life time supply for me as I use SE a lot.
