Absolutely! The snobbery on this forum is astounding (and quite frankly even disgusting). As long as you're happy and enjoying uni, that's all that matters. Some people may have the academics to go somewhere "better", but may feel unhappy at these "top" unis. The "Russell Group or nothing" group need to wake up and realise that there is more to life, and it most certainly does not make you a better person for being at a "better" uni.
For me, Plymouth was the best uni- because I'm happy there, love it, and wouldn't swap places with anyone for the world.
