Only way to be sure is to get out to the provinces and sample them for yourself. Reviews are subjective so lack of choice and the talents shown may well skew perceptions. There are plenty of skilled providers in London, mostly away from the massage scene, that a punter may have sampled and sadly found to be rare in the saturated market of the capital. Caucasian girls working in parlours are often younger and prettier and greedier and only top that with their degree of resentment for most clients, as reflected in the lack of performance when you do agree a price.
Chinese parlour women are typically older and plainer so less likely to have been lusted after in the civvie sphere, it makes them quite keen to fuck as a whole but most are pretty useless with oral and devoid of much sensuality, it's just they'd rather get 40-60 extra rather than 20 for the same time spent.
That said working in the provinces is reputedly less stressful as there used to be less clients (when not in lockdown) but as a whole they were better behaved and more likely to pay the asking price. Cost of living can be cheaper for girls free to choose where they work, no idea if girls moving around with an operation pay less though. Most girls would rather not work a train.
