Hi there, glad to have you join us.
If there's nothing wrong with your knitting style, you don't need to change it. Knowing both can come in handy if you do a lot of fair isle colorwork, but otherwise, stick with what gives you an even tension.
I'm another english knitter who doesn't make wild exaggerated movements and I don't see a reason to change. Though I can knit continental combined a little bit, I plan to use it only for teaching people who have trouble with english style. Like my sister in law who's been crocheting for years and didn't get on with knitting. I suspect she was taught english and she just had a hard time with it.
