What do you like best?
The overall functionality is extremely impressive. Using Webflow saves literally days worth of time, especially for prototyping. You have to see and try the software to believe it. It is extremely comprehensive, has a robust data store, and you can pretty much create any dynamic, hosted, database-driven website of moderate complexity. Some big names are using this software, and it can scale from landing pages to a sophisticated web application. Things that would take days or weeks to implement can be accomplished by adding a simple element or collection, and the code is very flexible. Though it is largely back-end-free and handled through a highly abstracted front-end interface, a JSON API is available.
What do you dislike?
There is quite a steep learning curve, and some of the options use non-standard terminology (presumably for ease of use for all audiences). There are really similar, difficult-to-distinguish icons right next to one another. Once you export code, it is final, so the feature can only be really used for prototyping. Another con (that goes with the territory) is that you're heavily linked into the platform, and that means you're going to be paying subscription fees for as long as that site is live. But considering the fact that you might never launch something with all of the effort involved—and that you get the benefit of upgrades—it's worth the trade-off!
