Well, I have all of them and find them equally durable and equally simple to apply.
The one thing that puts gelish slightly in front is that there are loads more fashionable colours to choose from.
Gelish and lechat perfect match do not need you to purchase a special lamp and shellac does.
Lechat perfect match is not available in the uk for another couple of weeks.
Given these circumstances I would select gelish, but that is not a reflection on the quality of the other two products.
