Is TPG really that shit?

I've heard not many nice things about TPG, but it looks to be one of the only 5G home internet options and the cheapest for the 50Mbps plan. Is it really that bad of a decision? Vodafone is the only other one that could provide me with 5G and it is $55 a month and then $65 a month after six months. Whereas TPG is $5 cheaper with the same size month deal.

While I'm asking should I go with the 100Mbps instead? I just bought a proper desktop and looking to get back into online gaming. I have only ever just used a hotspot from my mobile but I doubt that'll cut it. But considering I live alone will the extra 50Mbps just be a waste of money?
