Caravan leisure batteries

Good day to you all

I am not looking to start a free for all over battery names and types, but my orange leisure battery is on its last legs. I am looking to purchase a new battery, what battery make would you suggest as a replacement by recommendation. My ornage battery has served me well for the years i have had it, but just checking if there is anything better and to avoid the worse. Alos if you have any tips on what to buy
