I am only using them for sports and I switch because of price and selection of sports networks only. I don't consider the conveniences and general channel offerings because I don't use them for that. That's why I haven't tried out as many. If I were using them for general channel offerings I would have tried out Hulu, which I haven't. I also would have tried them all as apps on my tv, rather than just surfing to YouTube, Sling, and Fubo, which have less conveniences on the web as opposed to an on the tv app.
Also I switch when necessary because I am only using them for sports and it is less of a hassle doing so than it would be when watching general channels. They made me bite the bullet this month and I picked up youtube for the first time in awhile, because there was too many Espn2's & U's, CBSSN, and Pac12's in a row. I usually just pick up Sling when necessary, and add the sports extra pack when necessary. I probably would go with Hulu if I were watching general channels as well as sports, and put it on my tv instead of surfing for it. But I don't know that for sure because I didn't try it out. Also I didn't try out fubo as a tv app,(or any of the others) because I was only using it briefly, and it wasn't worth the hassle. (conveniences on tv apps as opposed to surfing include all or part of the following: not pulling down to the channel offerings when you accidentally hit an arrow button or the mouse, having and using the pip feature, the way the menu's work, having better control of things like flipping back forth with last channel etc. )
I am being so detailed here to make a point. Everyone's preferences are different, and different things mean more or less to one person/family than the other. Trying it out is the only real way to find out what you really like. It's like if I asked you what shirt was the best one to buy. Brand, color, pattern, price, & fit make that an individual thing.
Yes I would be a good product tester, and/or manual designer if that were a lucrative thing. I usually look for and/or test just about every aspect of most products I buy. I also am the one who less adept older folks call when they can't figure something out on there fancy new electronic doo dad.
I spent 40 hours making a manual for my mom & dad's newer car(Honda Pilot) recentishly. I figured I would at least spend 40 hours telling them repeatedly how to use things on it over the next year. That avoided the hassle of me getting aggravated at them, because they couldn't 'see' the directions I was explaining to them over the phone. It was all in the form of diagrams scanned from the manual, cut and pasted, and notated in photoshop with color coded arrows & steps, showing left and right, up and down, and circular motions as well as what buttons to push. I covered EVERY aspect of the car operation. It was the idiots guide to a Honda Pilot. I did the entire car in 8 easy to read large laminated 5x7" cue card diagrams, on flip page free standing ring binders.
Then my parents had the nerve to die in a house fire less than two months later. The nerve of them. Black humor is much easier now than it was 3 1/2 years ago.
