Please recommend my 1st Enigma2 STB?!!

Hello

I want your recommendation for my first Enigma receiver. I was digging for whole week and understood the main frame of this linux world, thinking to invest in cheaper model till I fully understand all aspects and I know that DM & Vu+ are the top, but Is it really matter?! Are all the same?!

My concerns and please answer this 🙏🏻

1-is Broadcom better 4k quality than Hisilicone??? By far??

2-is Hisilicone laggy as in octagon sf8008?? Or is this specific brand?? Is there a solution..?

My preferances as follows,

1-affordable cheaper is better but sadly I can pay extra for Vu+, if it is cost effective by far?!

2- 4k quality between them, a noticeable difference?

3- Dvb-s2x only?

4-perfect tuner for motorized 180cm dish?

If something extra rather than the poll option, please tell me 🙏🏻

Thanks a lot
