Laptop upgrade or transition to mini desktop?

[gash2024]

I'm currently running an HP 15-ec1001na for all my gaming needs but it's coming up to 5 years old and its starting to struggle, I've enjoyed sitting in my bed and playing but I have access to a TV I could use with a mini/Midi PC.
I have a budget of around £1k and I've seen a few like these that look ok.

Lenovo LOQ | 15 inch Full HD Gaming Laptop | Intel Core i5-12450HX | 24GB RAM | 1TB SSD | NVIDIA GeForce RTX 4050​

Acer Nitro V, Intel Core i5, 16GB RAM, 512GB SSD, NVIDIA GeForce RTX 4050​

Lenovo ILOQ 15IAX9, Intel Core i7, 16GB RAM, 1TB SSD, NVIDIA GeForce RTX 4060​

ASUS ROG Strix G16, Intel Core i7, 16GB RAM, 1TB SSD, NVIDIA GeForce RTX 4060​

Am I likely to see much difference with a mini, Midi PC? It would be nice to sit on my bed still but if its worth the gain I'll sit at a table.

Broadly speaking, if you're familiar with a laptop then I'd stick with it. There's something utilitarian about being able to use it from anywhere. Sitting at a desk can feel too much like work sometimes
