100-400 lens, Sigma vs Tamron, is WR important?

I was considering purchasing the Sigma 100-400 F mount, while it had been OOS for several months. It is available now, but I just found the Tamron one seems to be SLIGHTLY better in every way:

Aperture is slightly larger on the wide end

Slightly lighter

OEM tripod mount available

Better feeling when hold in hand (this is subjective though)

Most importantly, the Tamron one is fully weather resistant whereas the Sigma one is just partially WR.

IQ and AF-wise, I have seen different opinions, so I think it is a tie?

Unfortunately, the Tamron one is unavailable at this moment and I don't know how long I have to wait until I could get one. I hope I can have one for walking around bird photography next weekend...

Is there anything I missed in the comparison? I do hope Sigma has some edges over the Tamron so I can just pull the trigger.
