I happen to be a Hitec receiver and servo fan but you cannot go wrong by using JR or JR Sport. I do not think the standard JR Sport flight pack has ball bearing servos, if that is a consideration for you.

Like SST says, everyone has a favorite and they typically think it is 'best.'

For me, price is part of the decision when it comes to RC parts. I have mostly 60 size models and consider myself a novice sport flyer. The Hitec flight packs that include the HS425BB servos are inexpensive and give me what I need for the planes I have and way I like to fly them.
