This is always dependent on your use case. I travel a good bit and even though I have my phone with me, I think its a little bit of a hassle to go in and enable wifi through the hotspot all the time. Plus there are many times which I decide to leave my phone behind and just hang around with my iPad ... my calls/txt come through, and everything is seamless. As a matter of fact, for my kids ... because they are kids, I bought wifi iPad Mini's and every time we are on a road trip, I always have to hear the "Dad, can you put the internet on please" ... next time, im just getting them LTE iPad's and not have to deal with it ... I have a physical hotspot in the car, which makes it a little easier, but its not nearly as fast as my iPad, and the kids watch movies/youtube on our 12 hour drives. Again, thats my use case, but everyone is different and everyone has different patience levels.
