There's a
lot of factors at play when making a decision like this.
Do you drive a lot/put a lot of miles on a vehicle? If you do, you're probably better off with a hybrid. If you don't put a lot of miles on your vehicle, you may be better off not getting a hybrid.
Are you looking to purchase or lease a vehicle? Generally, if you plan on owning it for more than five years, you're probably better off with a hybrid. If you're going to own it for less than five years, you may be better off with something else.
Are you looking for good MPGs no matter what you do? Many people seem to expect hybrids to be a magic bullet to getting good FE. The truth is, if you're interested in saving gas money and getting good MPGs, you're going to have to be willing to essentially learn how to drive again. Hybrids, driven like hybrids, can yield fantastic MPGs compared to their conventional equivalents, but if you're not willing to learn how to drive them, then you may be in for a shock. (Driving styles can mean the difference between a 34 MPG tank and a 22 MPG tank on a FEH.) Or isn't that important to you?
You said you weren't happy with some of the displays with the Ford Escape Hybrid (FEH). Did you have the Audio/Nav system or a basic system on your test drive? That can make a world of difference! What weren't you happy about in particular? If you can test one with the A/N system (provided the one you tested didn't have it), I can pretty much bet that it would change your mind.
Depending on your financials and just what you're looking for in a hybrid, you may also want to test out a Highlander Hybrid. While a bit more pricier, and is more focused on power than FE than a FEH, it is larger, and may be able to meet your needs (EV around, roomy, etc.) better than the other hybrids.
You may want to check out the thread about why people bought their FEHs,
http://www.greenhybrid.com/discuss/w...-feh.4145.html (Which I answered in, and talked about the benefits both expected and not of owning a FEH.)
Also, there's an excel spreadsheet by MrFixit
http://www.greenhybrid.com/discuss/f...el+spreadsheet that you can download from that thread, that you can modify a bit to help you compare costs for a vehicle to get a rough idea of if or when you may be better off financially from a hybrid, or which one may better suit you in terms of pure money. (You can make some changes to compare two vehicles other than the ones there rather easilly)
Take some time to look at the forums and the real milage database, acquaint yourself with the hybrids. Don't be afraid to ask questions in the vehicle subforums. For some people, their hybrid is a tremendous asset. For others, it's a disapointment.
As mentioned, the different hybrid and hybrid systems are better suited to different tasks, but don't let that stop you from getting one because the other is better suited for it. We can't tell you which you should get, or which one is going to best for you without actually knowing you, but we can answer a lot of questions; we can provide you with the information, but it's up to you to do the homework.
Of course, if you're not willing to do the homework, or you're not that interested in savings, but you want to get a hybrid, buy a FEH.
