Mainly just looking for la liga and CL but UFC would definitely be worth it. I'm looking for a smooth stream that won't die out while watching a game, language of the commentary doesn't matter, I'd easily prefer a high quality (1080) stream over the commentary.
Also, whatever you recommend could you please also suggest how long I should go for (3,6,12 months?)
I would say go for rapid or a reseller of them They have the best most complete spanish package full HD sports channels and very good quality Also most of they sports movies documentaries are multi audio subtitles Rapid seem to have solved a lot of problems lately
