I agree with you - I wish retailers would dump the MX915s. There are a few chains that like the larger screens and use it for marketing but it is otherwise a beast that provides little benefit over simpler readers. My favorite reader (it feels kind of odd to have a 'favorite' reader, but whatever) is the Square chip/contactless reader. It just works, every single time, without any finnicky behavior. The vx8XX series is also good - again, these tend to be hooked up to simple POS systems that just work.
The 915s are almost always heavily customized and are often a crapshoot as to whether they work with contactless.
