Yes, there are many reasons to upgrade it, such as the new version is much faster than the old. Also, it lets you synchronize photos to use with the Lightroom mobile apps.
Speed increases do seem to be use case dependent. Many do see some increase, while many others see little to no performance change. There are even some who see a slow down of performance in the develop module, particularly those who make significant use of the local adjustment tools.
The Lr mobile app is quite good, you can download it to your smart devices for free, even if you don't upgrade your Lr version. As a stand alone product it is kind of OK, you can do a little work to your phone images. With Lr CC Classic (AKA Lr 7) you can also set it up so that you can synchronize images from your catalogue, from shared collections, and you get smart previews on the device. It's much like using Dropbox in that they are not published on the web. It also allows you to add phone images and they will be synced to your computer. It is much better than using say Dropbox and a watched folder. Because it is integrated to a degree it allows the images to be placed in folders of your choice, and will even automate folders by date. You don't have to add all of the phone pictures to the Lr app either. It's nice having processed but unpublished images to hand on my large screen phone to show to people, and to add images back from the device when required. All the time running comfortable old Lr CC Classic not the "new" web centric CC offering.
