Core differences between ultimate and premium tiers?

I live in NZ and we need to get GFN through a 3rd party provider (cloudgg) which doens't have all the options/details of the main platform.

I was on a 6 month half price ultimate deal, which was amazing. I think I'm going to go full price as the service is pretty impressive. However I was wondering if I could just go with premium over ultimate as it's about 30% cheaper.

The differences listed between the two on the site are mostly technical and graphics based, from what I could understand. I'm not that fussed about absolutely maxing graphics.

However I wanted to check what other differences there are that could impact my experience. A prime example being queues. I don't get queues on ultimate, but I see a lot of talk about them on here. This might be a non issue living in NZ but on the trial I got queues and it annoyed the shit out of me.

Any other considerations? I've been playing a lot of AOW4 and love that I can get in within seconds. Is it being pre installed an ultimate feature or would that work fine on premium as well?

Cheers.
