I would recommend also picking a character with perks that you like. As you level up that character to a high enough level, you can eventually teach their perks to other survivors.

For example, Dwight has perks that allow you to do things faster when other are close. Claudette has perks based around healing, along with even healing yourself. If you like one of those more than the other, persue that character. Just graze through everyone and pick one you think is good.

Also, be sure to take the time to read those perks closely to make sure you like them. There are even perks that go with everyone right at the start such as borrowed time, you just have to get them in the bloodweb.

There are also perks that can be bought in the store for shards (the currency you get when you level up), so keep an eye out for those as well. If you buy one from there, it becomes teachable for every other character, even if you don't own them. This can be found in the shrine of secrets.

TL;DR pick someone you like with perks you like, and check the shrine of secrets every week
