Hello, I would like to purchase Spanish frigate, and I am struggling to choose from:

-Mahonesa 1789 / Ninfa 1795
-Diana 1792 / Proserpina 1797

is there any significant difference between those two? Anything I should take into consideration, when making decision? Sorry if my question is dumb, but I am pretty new to the game. Thanks for understanding. Looking forward to your suggestiopns.
