I do use the whole focal range at times and have gotten shots I never would have gotten if I had a 600 prime. But most of the time it is at 600 or just under. A 600 prime is way out of my budget. I would give up some zoom with a 300 and tele but most likely better image quality. I have a 100-400 II and I tried it with the version 3 tele and I just couldn't get the image quality that I got with my 150-600 and it got worse in low light which is where I probably shoot most because I like to shoot wildlife. I am using a 5D4 for my camera and sometimes my 7d2.
Just remember that the shorter zoom range is optically going to be better across its range than a long zoom range. 4:1 zoom (150-600) will be better than 10:1 zoom (60-600).
You sacrifice more in having a one-lens solution to cover wide range of FL. Notice how lens tests who conduct objective tests of performance on lenses generally do not bother to test the superzooms?! A review of superzoom bridge cameras summarizes
"But if you like to pore over every fine detail of your images at 100 percent magnification, you’ll be disappointed every time; buy an affordable mirrorless camera instead. With a superzoom, you’re paying for the convenience of leaving a bunch of lenses at home, not for pro-level image quality."
Admittedly, testers were generally impressed with the 10:1 zoom's performance, exceeding the expectations most had of superzoom based particularly upon historic patterns of performance.
Perhaps you can cancel the order for 60-600 and tell the retailer you changed your mind before it arrives.
Then you could bring along a 24-105mm to complement the 150-600mm...you would not mist the 105mm - 150mm 'gap' much at all. Or a 70-200mm so there is overlap with the 150-600mm to reduce the amount of lens changing.
