Of course they differ, also Cypionate isn't a good ester, I consider it the worst after Suspension
Testosterone Undecylenate is the leastest ester to Aromatise in my opinion but very hard to find, also Sustanon is very good as it has the properties or less peak/more duration than others like Cypionate which starts with peaking level after about 48hours and decline rapidly which increase the risks of aromatising
