Standard Life, True Potential and Wealthtime have emerged on top of a survey of some of the major wraps and platforms.
The latest analysis from the Finance & Technology Research Centre (F&TRC) looked at eight different services, benchmarking them on all the adviser-facing areas.
It included over 9,000 questions, covering 150 areas including cash accounts, benefits statements, transaction history, re-registration facilities and tracking facilities.
The survey was formulated after extensive discussions with advisory firms about their needs and expectations from wraps and platforms and each provider was measured against the same objective scoring model.
Ian McKenna, managing director of F&TRC, said: "A steady stream of new entrants combined with significant growth in the range and depth of services delivered by the existing platform community makes it increasingly challenging for advisers to be able to measure the full range of options available to them."
With the rapid expansion of the wrap and platform market in recent years, he also suggested there would be more developments before the sector stabilises.
"On the one hand it is hard to see the current numbers sustainable but, on the other hand, there's a lot of innovation out there at the moment," he added.
"For the next few years we're probably likely to see even more players enter the market with varied success."
Eight providers participated in the survey, although it was open to all the current wraps and platforms.
Here's how each service was rated:
7IM - ee+
Ascentric - ee+
Aviva Wrap - ee+
Axa Elevate - ee+
Fidelity FundsNetwork - ee
