What (specifically) will you use it to detect? Where? All Metal detectors are compromises and tend to target specific goals. As a result, there is no 'Best' detector, it all depends on what you are planning to look for and where. For general purpose Coin Shooting, they are both good at it - however your familiarity about the nuances of the operations of the detector will determine how well you do with it (expect 100 or more hours of use with your detector to get to that level).
If you are dealing with wet salt water beaches, expect most VLF type detectors to work poorly. If in highly mineralized ground (common in mining areas), you need a Detector that can be ground balanced (and you need to learn how to do that with the detector). If you are in an area that is loaded with hot rocks, you may not be able to get any VLF detector to work well.
I have 9 detectors, there is a lot of overlap in the ablities of some of them, but all have some speciality that makes them better suited for specific tasks. I have all of them because there is no 'Best' detector (I want to add a PI detector to my collection, because I need that ability in some areas that the VLF detectors I have don't work well enough).
You will find that either detector is a good match depending on what you are looking for and where you are looking. Anyone's opinions will be based on what they are looking for and where - if they are not the same as what you are planning to detect for or on vastly different ground, it may not mean a lot.
Its like the vehicle you drive - whats better, a Toyota Prius or a Mercedes Sprinter Van? It depends on what its supposed to be used for (by the way, I drive a large Sprinter Van - it hauls all of my wife's mobility gear and still gets around at 24 MPG; she's handicapped and none of her gear would fit in a Prius).
If you have no experience with detectors, you are better off finding someone local to you that can show you how they use their detector and what types of targets they go for. If there is a metal detecting club in the area, you might want to visit it to get opinions on a wide variety of detectors. You'll also find people with different interests (and biases) that might point you to a better match for your needs. Not everyone likes clubs, so you don't need to join one, however if you are spending a lot of money on something, its probably a good idea to make sure that you will be happy with what you buy. 'Best' is relative.
