How's Sun King Solar?

Got an offer from Sun King Solar My current company is very good in all aspects but Sun King is ready to offer me good package, I mean real good.

I'm confused, should I get in touch with my current firm and tell them what I'm being offered and negotiate for something here or what?

If SunKing is good, like if anyone is currently working here, hmu please, want to know things before making a move.

Thanks in advance.
