I think you must mean “brokers,” not “platforms”? They’re very different things.
The only “platform” to avoid, in that context, is the one called MetaTrader 4, because there’s a thing called the “dealer plug-in” available for it, which was invented specifically for crooked, unregulated brokers to be able to manipulate the prices against their customers. Beware of brokers not offering you a choice of platforms (most do) but forcing you to use MetaTrader. That’s a very, very bad sign.
CTrader and TradingView are both much better platforms. There are others, too.
The only really important thing is by which regulator your account’s regulated. Getting just that one thing right gives you probably a 95%+ chance of avoiding serious “honesty problems” with brokers as the properly regulated ones can’t get away with anything underhand or crooked.
The “proper regulators” are the UK’s FCA, America’s CFTC and NFA, Australia’s ASIC and all the European Union approved regulators. Those are all legitimate ones, so there are hundreds and hundreds of decent, honest brokers to choose from, and almost all will offer you a choice of platforms from which to trade.
