Mining supporting wares in BTC.

I want to know more establish machines that are best in mining Bitcoin in a sophisticated method that will flourishes Bitcoin mining without failure or errors in either upgrade or security related issues later on the gadgets or machines that crashes every effort of miners.

Go to this website and select the BTC coin

You'll find all modern ASICs if you sort by release date.
First, research the main manufacturers on the market and their products.
The table of the main ASIC manufacturers and their market share looks something like this:

Bitmain 60% - 70%
MicroBT 20% - 25%
Canaan 5% - 10%

Once you've researched this, you can ask more specific questions.

I don't think there's an ASIC unit that doesn't experience any issue, hardware or software issue, but what I can suggest is choosing a miner that has all cheap replacement components available on the market; at least you can repair and replace it easily when the unit has a hardware issue. I think the S21 series is a better choice for this that can later be flashed with custom firmware (except for AMlogic).

The s21xp would be a good choice.

My 9 are all working after 17 months of mining.

The S21 series is quite reliable, but at the current Bitcoin price, miners need very cheap electricity to make a good profit, recoup their equipment costs, and still be able to buy new ASICs after the halving.
Small miners are going bankrupt in the market.

There's no such thing as a perfect machine that never fails. Even the best ones still need regular maintenance.

What kind of equipment doesn't need maintenance?
If you give a fool a crowbar, he might break it, even though it's very difficult.
Mining equipment becomes obsolete within a few years, and you ideally need to recoup its costs within 12-18 months and then earn enough to buy new equipment. You won't be able to mine with old equipment for five or more years unless you have free electricity.

I have had thousands of gears run under my hands, mainly from these three brands (Bitmain, MicroBT, and Canaan). If I were to be fair, I would exclude Canaan because I bought most of those used, and they were a complete mess. With that said, MicroBT was an order of magnitude more reliable than all the Antminers I had, with the exception of some variants of the S9 (not counting the S9k).

It's worth mentioning that the results of my experiments, which lasted for years at very different scales, were also done at very different places with completely different environments. We had small to medium-sized farms that were a complete mess with cooling and other farms where miners ran in perfectly air-conditioned facilities. The results didn't change much,MicroBT still beat Bitmain at every single level.

However, to be even fairer, if you were to focus on a single component, which is the PSU, then MicroBT vs. Antminer would likely be a draw. However, when it comes to the control board and hashboards (the most expensive and hardest to replace component), MicroBT has always been better. I literally had some old M20s that ran with a single fan while the heatsinks were completely covered in dirt. Nothing but an Antminer S9 would go that far.

It's also worth mentioning that with Antminers, it's a game of luck. Different batches from different manufacturing locations give you different results, so you could get a good batch today and a bad one next month. After all, it's Bitmain. Does anyone recall the 6-month failure report from the large Chinese farms back in the day, when Jihan Wu had to apologize and send his technicians on-site to fix those miners? Was it 30% or 40%?
