I won't tell you which one to buy, you will discover you genuinely need to own both of them for true cosmic happiness.
Buy in the best condition you can find for your price. Don't be afraid to pass on the Lee-Enfields for a little while, they're still available. The Swedish Mausers are now uncommon, but not scarce.
The Mauser is a better-made rifle than the Enfield, but Sweden was not engaged in world war, either, so they took the time for fit and finish, despite some fear of Russian or German invasion. The Enfield is a fast battle rifle, well-designed, arguably the best bolt-action of WWII. Jerries and Japs did not like it, one bit.
