T-pose or A-pose for AI auto-rigging?

I've been playing around with AI character generation and noticed how much the starting pose affects the rigging process.

I've mostly been using a T-pose with V2Fun, since it makes the shoulders, elbows, hips, and knees pretty easy to identify.

But I'm curious what everyone else prefers.

Do you generally use T-pose, A-pose, or just whatever pose your rigging tool handles best?
