Grand Cherokee, Pathfinder or L 200 to start offroad?

Good day to all friends. I have a couple of questions. I will be glad if you share valuable information. I’m undecided between Grand cherokee, L200 and Nissan 2000-2001 pathfinder. In addition, as a newcomer to offroad, should I buy a built vehicle or do it myself, it would be more logical and economical. I am looking for a vehicle that will not be afraid of hard offroad but can offer a comfortable exploration tour. I would be glad if you share your information and suggestions. Thanks in advance.
