I favor all plants. The needs of corals and plants are pretty different. I think you'll have more success focusing on one or the other.
It almost requires a full mind shift from reef tank to plant tank. Instead of keeping nutrients super low, you need to keep them high for plants. You may find plants more challenging than expected. I think plants help you to think of your tank as more of an ecosystem, rather than a box with a bunch of life support gizmos.
And if you turn out to have a green thumb, you can always add corals later.
Best of luck with whatever you choose to do!
