Ideal and Wago's are both rated at 32A when not used in maintenance free mode. For maintenance free installation you have to down rate them both (to 24A)
And these connectors are only ever maintenance free when installed in compliance with the maintenance free instructions supplied with the connector boxes (Wagobox, Wagobox XL and Wagobox XLA for Wagos and the In-Sure box for the Ideal connectors). Using them in any other way means they are not installed in MF mode and must be accessible for inspection.
My personal preference is Wagos because of the availability of the various Wagoboxes.
