Plus gas for glow plug removal prep, which one?

[Big Rig]

Planning on changing the glow plugs in my 1.7cdti Astra. Was going to start soaking them for a few days before to try and help them come out.

There’s 2 different ones on Amazon, which one is best? Or is there anything better than these available?
