Basically the foremost decision is on your side.But let me make your way easier to decide.As you have cleared your JEE mains and ready for JEE Advanced,the confidence you have is all what matters .If you feel like the colleges you get based on (All India Rank) AIR is good on comparing with EAMCET college you got then go for it.But take your decision before freezing your EAMCET seat.Your knowledge and confidence is everything.
