Southpaw or orthodox?

My left hand is a decent bit stronger than my right and I’m much more confident when punching whereas my right leg is better when kicking (my left leg is technically stronger due to a recent injury and me losing muscle in my right but I hit harder so idrc) I’m not sure wether to fight from primarily southpaw or orthodox. I’m just wondering whether if there is a massive advantage to having the left hand at the rear. I’ve been doing Muay Thai for about 7 months now and have had 7 interclubs and I’m used to orthodox but can fight from southpaw. Just wondering whether to get used to southpaw more or not.
