Yes, because of SEVERAL excellent reasons:
1. Boats are cheaper.
2. Boats are faster.
3. Boats are carryable, meanwhile striders can only be forced around with a leash.
4. Boats can now hold chests, whereas striders aren't.
5. It saves you the hassle of trying to tame something that resides in LITERAL LAVA without risking your hardcore world that you fear more about losing than your 4-year-old baby.
6. If you lose a boat, you can craft a new one in 5 seconds if you have the available materials, instead of spending hours on end trying to tame a "Lava Jesus" as I like to call them, without DYING.
7. No need for trying to find Warped Fungus to put on a stick to navigate these wannabe pigs in a nether mob's skin.
