sidehack is making usbsticks using more recent chips... However, if you calculate the hashrate vs the power usage plus the extra costs for a controller and a powered usb hub, i don't think they can compete with an S7-S9 (didn't bother to do the math)...
Sidehack does a great job, but AFAIK, his sticks are best for hobby miners, education or playing blockchain lotto.

for sure if compare with S7-S9...
what is the best for mining hardware since bitcoin difficulty very high...
i try some altcoin but still no good result

At this moment, nothing tops the S9 (afaik) when talking about Joule/Ghs. That being said, you'll still need a sub 7 cents/Kwu electricity rate if you want a shot at making profit (there are many other factors, but the electricity rate is the biggest)

yup...electricity is very expensive even in my place indonesia...also not so stable

DIY is largely for entertainment or learning purpose these days.

If you are serious about striking a profit, you will have to go with one of those commercial ASICs.

Efficiency wise, S9 is the no-brainer to go. Followed by T9/A7/E9 pretty much at a second-tier but still decent level. Do note that the later 3 all have noticeably more improved reliability over S9.

Having access to cheap power is also critical. GL.
