What would you rather use

a max sword +15%/-5en, +15%/-1 health regen, +15%/-10 armor, or +15%>50?

Personally 15% -1 Health degen. What's so wrong? easily brought back up by monks, can switch when not in battle so that you don't have constant hp degen, and if you are a wammo paladin then you have that useless excuse for a spell, mending.

Personally I'd choose enchanted but that's not up there >.< but out of those choices for just playing i'd choose -5 eng because most of my builds only require about 20 eng and with glads armor and that sword equipped i get 22.

15>50 or 15% -5 energy.

15^50 or 15% -5 enrgy

depends on build..
ill never go for 15 - 10 armor since i believe armor is the most important thing in this game for pve
in pvp the armor doesnt really matter since as a warrior u dont get ganked on.

15>
15 - 5 imo

15>50 or 15% -5 energy

thats... just... impracticle, might as well use 15%(while enchanted) and have 1 pip higher regen
