Yup, the 1634 has been getting some love. If you can do QFN (or VQFN), that opens up plenty of more options.
I’ve been using the attinyX16/X17 lately (such as the ’816). They’re also QFN/VQFN with plenty more pins, but they use a newer architecture and programming/debugging style. That may or may not be a good thing depending on what you’re going for.
