I completely understand the desire to restart for various reasons, but having seen quite a bit of content from the Dark Urge and playing through custom myself, I wouldn't say Dark Urge is "basically a better version of Custom." If you want a more defined story for your PC and/or really feel like you need the extra gear, abilities, etc., then sure. However, for anyone that wants to define their own character and not have to deal with potentially killing characters they like (whether through DC fails or in a very few cases, having no chance to combat the "dark urge" at all), then I think Custom is a much better option.
Not trying to discourage your choice or anything - play how you wanna play. I've just seen too many people start as Dark Urge because of people saying it's a better version of Custom, only to have them restart because they hate having less agency over what their character does. Hopefully, it's what you're looking for out of your playthrough and you can enjoy it, though.
