Just to answer the answer in title. (and some thoughts along all answers)
For me NO. There is no better SCADA than Ignition.
Started with PLC programming about 25 years ago and with SCADA 20 years ago. Used to be RSView32 which I agree has lots of limitations , but for me was very good as it was stable. Still, have some applications moved in VM over XP running like the first day. Since then, I have been through a lot, RSViewME, SE, FTView, WW, WinCC->TIA, Citect and others, and cannot say which one is worse. (Probably the one I am working on it on that time).
Around 2008 I have discovered Inductive Automation, registered on site , downloaded test software, but being busy did not try it. This is one of my biggest regrets, could have saved me lots of headaches, also could have get the free edition of Panel.
In 2016, after lots of headbanging decided to try again. Registered to IU, registered as integrator, after one year got certified, now waiting for gold. Using Ignition feels far away superior than anything else. Sure it have bugs, sometimes slow etc, still does not compare with competitors issues.
I have been about 4 years RASI, system integrator with RA. Help from support was a real jungle fight, through several layers of people without knowledge up the skilled ones with a primary goal to prove only that you are wrong, not to solve the problem. Several times had to appeal to management to get firmware fixes.
Even better with Siemens. Bought licences in the ten of thousands range, what we needed was not working at all, after months of discussions finally they agreed there is a problem and to be solved next firmware update. Perfect. So when it will be? Aaa, as usual November.Wait, but is April , need to start-up in June. Sorry, November⌠OK, we worked like crazy for a workaround. November came. Please update.Aaa, no, sorry, this piece of software is not anymore in our portfolio⌠. Imagine that. ( By the way , noticed that usually Siemens people are rigid and just living in their own bubble. They are living in Siemens world and they are finding very difficult to understand easier, flexible things)
So Ignition came along as breath of fresh air. Fast installing, you can see tags right away, no need fancy simulators, running on Linux, unlimited testing time, integration with free sql databases and so on. Support? Actually never submitted a ticket. Had some questions, answered right away on forum.
Therefore bugs and other problems are, again, by far more bearable than in other SCADA platforms.
