i have been into mixed martial arts for little over two years, and am really interested in taking it up. I have been doing bjj for over a year now and am comfertable with my ground game now and wishing to learn some stand up but i dont know what style to learn can you guys help me out?
There are several threads around that deal with your kind of question. I would say that it's not to useful to absolutely generalise, because in the end it depends on the way the respective style is taught in the specific gym you go.
What kind of styles are available to you in a reasonable distance¿ It wonn't help you if we tell you to go for X if X is not available in your area.
the gym near me deal with boxing, muay thai and kick boxing?
Then go for Muay Thai as your main stand up training, but as there is the possibility look from time to time into the other classes so you have training partners that react in another way and are specialised on specific aspects.
As mentioned earlier it's more important to find out about the specific gyms you have open to you rather then just say a style based on name, if the MThai school is teaching a really watered down form of MThai you won't gain anything really solid out of training there just because of the name on the door.
If everything is equal tho I agree that MThai is the best pairing with BJJ while Boxing and Wrestling tend to work well together. Obviously you want to train in a bit of everything but in general these make effective pairings.
