Your prescription isn't very high. I have -4.50 prescription which isn't too far off of yours and I've been wearing contacts for the past 17 years along with glasses. Can I ask if you know if you have an astigmatism? That would be the second number on your prescription underneath the "cyl" column. A high or irregular astigmatism may change my opinion.
I would encourage you to try a soft lens first before using gas perm lenses. For ease of use and care as well as comfort. Many brands have lenses that allow more oxygen through the lens and are disposable daily, weekly or monthly depending on what you prefer.
Gas perms require more delicate care and must be fit by someone with a great deal of knowledge as it has to match the curvature of your cornea to achieve the most comfort and stability. Really I could go on for ever but I'm probably gonna bore you with lame facts. So I recommend you to go soft lens and go from there.

Thanks for such detailed comment
I am not 100% sure whether mine is polycarbonate but I am sure that I got a high index lens and the distortion is too much. Having to work with two monitors, I need to look at the screens directly in order to overcome distortion, which is irritating (1st world problem
).
My right eye does have a -0.75 cyl and left has none. Never really bothered about that number (I had none for both eyes until my most recent checkup last year. Wonder if that will be an issue with contacts.
Yes I do agree GP has some major drawbacks (comfort and correct fitting will probably be the most important ones to me) but there are too many people complaining about blurry vision through soft lens online. Since you have been wearing them for 17 years, what's your experience?
