While I don't currently own razors from all of the categories in the poll, I do enjoy experimenting with different razors and I hope to eventually own one model of every razor ever made.
I've been wet shaving for nigh on two years now and have only ever used one DE - my Merkur HD. I am looking to buy a slant though as I feel I'm ready for a change.
I'm addicted to SEs. I had a Parker 82R with IP Reds, but I had such a better shaving experience with a Gem Featherweight, I haven't gone back to DE yet. I might, at some point, but not anytime soon.
I own a Merkur HD, Merkur 39C Sledgehammer Slant and a Gillette SuperSpeed. Since I received my Slant in the mail back in November I have used it exclusively. I doubt that will last but so far I have not had the itch to go back to the others.
