Lenovo is much better than Dell and has announced a lot of Ryzen 5xxx laptops. Not sure if the Thinkbooks/Thinkpads are available yet but they are coming.

AMD just caught up (to Intel) in 2020 in laptop efficiency, and the OEMs are starting to catch up in offerings in 2021. However, availability is a mess in general lately. Might be 2022 before really high-end laptops offer Ryzen regularly.

Pretty much all major laptop vendors have Ryzen 4xxx models. Some like Dell only put them in their lower tier models.

5xxx models are just appearing, look up the Zephyrus G15.

The M1 is honestly very good value and the overall best mobile chip right now which is rare for Apple. Unless you need a PC. Goes toe to toe with my big desktop machine on dev workloads.
