I've been using Snapcut in parallel with SubMagic for a few days.

PROs
- Easily upload videos or use YouTube or other social links to ingest content
- Selection of fonts, effects and transitions is great - don't need 100 options, if I only use 5-10
- Branding is easy to apply from video to video
- B-roll can be inserted by selecting words and using Pexels as a source - it gets the job done (it's better than nothing)
- Very good transcription for multiple languages (speech to text)
- You can export the subtitles alone, for use in other tools (ex. Premiere Pro, DaVinci Resolve) - huge functionality for me, to be able to play around with timings, durations, colors and fonts in a different environment

CONs
- 2 GB Limit is small for file uploads - but I got around that by uploading an Unlisted YouTube video and it worked great.
- Speed isn't as high as other tools (SubMagic), but you only have to wait a few minutes for a 60+ minute video - which I found to be more than acceptable
- Only free B-Roll at the moment - and the associated user experience feels a bit lacking at this time
- Haven't seen an upload-your-own-font functionality, to help keep things even more on brand

Overall, this is easily a 4.5/5 tool, looking forward to more improvements on the roadmap.
