Is it worth it? Depends on what you're making.
The quality of the seedance 2.0 in topview is actually somewhat comparable to runway. However, once you burn the credits, the waiting time for the unlimited generation takes 2-12 hours. You can cue up only 6 video generations at a time. So, probably an option if videos are short or you don't make a lot of videos. If you need to make a lot, probably not the best fit for you.
