Is it worth it to upgrade my main 3x3?

So basically i will buy some cubes soon and dont know if its worth it to upgrade my 3x3 main. I feel like i could spend the money from the 3x3 in something different like a new skewb or smth. So currently i have a Moyu Meilong M V1 and im thinking of upgrading to a Dayan Guhong Pro Maglev. Is it worth it for the 20 bucks? Or is there something cheaper but the same in terms or performance of better? Thanks in advance :)
