This is by far the best drawing/painting app for iPad. I wander off to the others occasionally (Procreate, Artrage, Pixelmator, etc.) and they have their good points, but I always wind up back using Sketch Club. There are several reasons for that.
1) It has the most complete toolset. Brushes, procedurals, pens, vectors, its just all there. It has an excellent set of filters, fantastic layer support, selection, copy/paste, image import...basically anything you can think of.
2) The new brush update is simply amazing. You now have both a shape, AND a texture to work with. These brushes can do anything.
3) Apple Pencil support is excellent. I use an iPad Pro now, and so Pencil support is vital. Using the Apple Pencil with Sketch Club is a revelation...so accurate, with decent palm rejection, my iPad can finally completely replace paper for any kind of artwork I want to do.
4) The community is great. Im not big into social media, and I think its a bit unfortunate that Sketch Club has the name Club in it...makes it sound like the app is completely focused around the social aspects. But the truth is, the app is a very powerful drawing and painting app, and the social stuff is "extra." However, having said that, the community is very friendly and welcoming, and Ive really enjoyed sharing my artwork there. Plus theres a "Livestream" feature built right in, so you can watch (and hear) others as they create stuff, attend (or give) lessons, etc. No other art application has this level of support for community. Ive found it quite enriching.
5) The app almost never crashes. Its so rare, Ive really only seen it crash a half dozen times in my 4 years of using it. And when it does crash, your stuff is still saved. Ive never lost a stroke.
Cons: There arent many. I think the UI for the social part of the app has become rather cluttered over time. It has a lot of cool features, but its a bit disorganized. The web site is having a few growing pains. SC has become more and more popular, and sometimes the site is a bit swamped. Theres so many new sketches every day! But thats also a plus, I guess :)
Bottom line, this is the app to have. Very highly recommended.
