I would definitely recommend sovs for the reasons that have been mentioned above, but be warned, there is such incredible variety that buying them can be a little addictive. But having said that, there's always half sovereigns as well if you want to get more diversity for your money

In my opinion, no coin is a waste of money if you find it beautiful and interesting and want to add it to your stack/collection. Will it go up in value over time? Maybe, maybe not. But if it brings you enjoyment then it's a great purchase regardless.
