The SE is desired because it has a full size 1 3/4 agathis body. Most Bullet and Affinity models are thin 1 1/2 bodies. The SE measures 42mm at the nut. Most Affinity models have 41mm nuts. They were made well, have fantastic 9.5 radius C shaped necks and they are just an all around perfect modding platform. They are very easy to identify due to the logo just saying "STRAT" on the headstocks, as well as them being the model of Squier to have a Squier logo stamped into the sealed tuners. I think most people consider them in between an Affinity and a Standard as far as quality.
