The O2 network here is terrible for 4G I agree the other two are much better.
Is the lower priority actually noticeable though? Like have their been any third party tests? I'd never heard that until today but it does make sense I guess. They want their own traffic to come first.
The question is, which level of LTE? If it's capped at anything between 10-15 MBit/s there will be no advantage over HSDPA, versus the 150+ MBit/s you can get via proper LTE.

Yeah, but markedly more expensive.

Go to any bigger event, say a huge anti-nazi rally, Oktoberfest or rock festivals. I was in Cologne a couple of weeks, approximately 20k people attended. My LTE tablet (O2) had no internet at all. My business phone (Vodafone) had proper internet access, and my private cellphone (Lebara, using Telekom network which is inarguably the best) had massive issues.
Also, all non-first-class customers (i.e. everyone except direct contract customers of the three telcos) get lower priority on the network, both for calls and data.
