I have been using Edge since Win 10 first came out, both at home and professionally teaching and have had no issues that are unreasonable, even if some might not be my first choice. The odd exceptions are that with an update it has several times reset my page on opening Edge to the default one (but not reset the home page) and on one update the schema for security changed and so all of the choices had to be remade. Edge was originally Win 10 only, but has recently become available for Win 7 – if downloaded it could be installed, but it would not be installed by a Win 7 system automatically, as it now is.
Internet Explorer is too out of date to be recommended and many sites do not respond to it. A point to remember is that a clean install of Win 7 puts an even older version of IE on and this has to be updated or replaced before some other updates will install.
Chrome used to be my browser of choice but over the last year I have been encountering more and more sites that will not respond to it.
Chromium on the Raspberry Pi is reliable, although with some sites it selects the mobile phone version for some reason.
Opera, which should have the best support for HTML5, being developed by some members of that team has never appealed, although I could not tell you why.
Firefox I use on Linux boxes (and also portable apps) because I have had issues with Chrome not installing correctly with some distros when Chrome has been added in addition to the standard software setup. It is also my browser of choice for XP systems.
Of course on the Macs and iPads there is always Safari, but I am not a sufficiently major user of these devices to assess tit in depth.
Finally Lynx is a text only browser I installed when setting up an MsDOS system recently (I was playing – OK?) and while the results in today's graphically rich internet were sometime strange, it did work.
The bottom line for me is to accept that differing operating systems come with different browsers and the default choice is rarely a problem, and never as bad as 'people' will suggest and that if it does not suit Firefox or Chrome will often be valid options. This Win 10 system has Edge, Chrome, Firefox and IE installed although 99.9% of the timer I use Edge.
