I think everybody' best glove is related to their environment and personal choice. Seajays environment and needs is certainly different than mine and will influence each of us. But I hope to think out loud here and present information so we can all make a good choice on solid info.
I'm certainly no expert and welcome input and rely on everyone to fill in any blanks.
So my basic kit is a rebreather, fusion drysuit, and ultima ring system. I dive on Great Lakes shipwrecks as well as freshwater quarries. The water is always cold here, even in late summer, it's 38f at depth. So I spend a lot of time and energy to stay warm. My Achilles heel is my hands, when they get cold and hurt, it's difficult to solve problems and have fun.
I really think the basic factors in making a decision is fourfold. This is my order, yours may be different.
Fit- if they don't fit it's a no starter.
Tough/ dry - if they won't withstand the daily rigors of your diving and open up, that defeats the purpose of going dry.
Dexterity- being comfortable and able to manipulate your gear is next for me. I have spent years dive developing skills to work with dry gloves and insulation. It ain't easy. I dream of diving warm water someday.
And lastly, Warmth, which is influenced by the material the glove is made of. I defer to Seajay on this one, as nitrile has the best insulating properties, so I have tried to emphasize this material.
I've listed in the spreadsheet the gloves I have dived or have on hand. Included is the material and toughness, EN388, testing, specifically. I'm going to let this info settle in, and I'll make comments on each glove, stand by for that.
