I have experience with all of these heads. The vented Wensel Elites I own are too small/narrow for my liking. The 300 XTREEMS are as solid as any head I've ever seen, but some guys find them too expensive. A great head nontheless. In my opinion the best all-around choice of the three are the unvented Terminators. Well made, arrow dynamic, great penetrators, and easy to sharpen and keep that way. Priced well too. I am currently using the 250 grain screw-in models, but VPA offers a wide variety of other weights and widths. Good luck!
