I reckon if you're only going to have one razor, then an adjustable is a good choice.
I like to have two. I have a Muhle DE89 (with knurled handle, same head as the EJs) and a Merkur HD.
The HD is far heavier and is a more aggressive razor. The blade gap, angle, and exposure are all greater than the Muhle.
The Muhle is a notch or two milder. I use this on days when it's only been one or two days since the last shave. With a blade like a Super Thin or Crystal/Red Personna, it's a close, comfy shave and almost impossible to nick yourself.
However, I usually only shave 2-3 times a week, and for that the HD excels, particularly partnered with a Feather blade! I sold my Slant as I found the HD to shave equally as well, and was easier to use.
The HD is a fantastic razor.
