Is BitBucket the best choice?

I am starting a project which will involve various developers, some offshore. I need a GIT Repo I can use for source code management and have good memories of BitBucket.

Is it still a great choice?

I saw a difference between Free/Standard/Premium that I dis not understand...

"Build Minutes"...

I do not recall using BitBucket to Build anything. What does this mean? To Build on BitBucket??

This site will have a EJS front end with a JAVA back-end. Does this mean on JAVA code commits, an auto-compilation can be configured? That is probably an option, I presume...it may be a very good option, but I'd like to understand it.

Thanks
