I almost always use the group finder. If I need to farm gear then depending on the dungeon I may do it solo with a companion, or with guildies. If I just want to run dungeons or pledges then typically always group finder.

I do all the options, duoing and duoing with group finder being my next most frequent choices. However I am in a dungeon group where we play at least one a week for three hours, so I choose that as the most consistent option.

Before the dungeon group my most frequent choice was queue in a duo.

Depends on the day. Some days are easier to run with friends and guildies than others. But I tend to run a random normal on days when I don't like the pledges, i.e. Darkshade 2

I don't dps

If i found anyone on the pc server who actually liked dungeons id for sure wanna do some with them. Unfortunately that hasnt been the case so the only choice i have is the dungeon finder.Which of course you run the risk being grouped with others with different expectations of a dungeon run.

Solo for vanilla pledges (or queue as a tank if I'm lazy), group finder for dlc ones. Premade groups if I'm doing some achievement.

There isn’t a single answer for me. I would guess that’s true for most players. I prefer guild mates and/or friends but will do a pug if needed. Since I want the transmutes I need group finder either way. I will solo if I’m farming a set (if I can).

Almost exclusively premade for vet, normal mode random if I level up something new.

I put Other because I don't actually care

I enjoy the challenge of pugging as it keeps your standards up. When I'm just getting my 6 RNDs done for the day I don't really mind whether I am solo or if someone else is doing RNDs in guild I'll go with them.
I like the variety of going solo, duo, with friends, with guild members, with random people on the rare occasion I do pledges etc as variety keeps things more interesting.

While there are days I'd be happier not to deal with random players, I could never get behind an MMO that wants players to play on their own - it 100% belittles the intent behind sharing a world.

Only solo with companion. I left ESO for like 2 years, came back about a year ago and figured this time I approach the game as a single player experience. Having a blast ever since, especially when doing dungeons solo for the first time.

It is for me one of the best experiences in the game, to have all the time in the world to listen to the NPCs and especially in the newer dungeons they have a lot of interesting things to tell in-between their quest dialogs. Explore every nook and cranny and occasionally stop just for a moment to look at a stunning view. Some of the dungeons I believed to know in and out from the past years turned out to have some really amazing looking spots I just did not notice while rushing through with a group.

Sometimes I do it solo, but only for gimmick and secret searching.
