of al the comments i’ve ever seen about TradingView (which do include some complaints, as well as very widespread praise), i’ve certainly never heard of anyone switching back from TV to MT!
i honestly find it very hard to imagine that anyone could
it’s one of those subjects on which there can be varying opinions, though, depending on who/where you ask
if you ask in a forum for forex beginners, sadly the huge majority of the members are using MT
if you ask more experienced traders, long-term profitable traders or professional traders, you literally won’t hear a single recommendation for MT, just a lot of warnings about it, some more strongly worded than others; you’ll hear from a lot of people who like TV, though (and for good reasons, IMO)
the comparison you’re asking about, IMO (many here will disagree with me, obviously - nothing new, there!), is between one of the best trading platforms and the world’s very worst
