It really is a matter of paintball masks for paintball
The following is a recent test by PBM Paintball Magazine of a dodgy set of goggles, it shows how something that doesn’t cover the standards just isn’t fit for purpose.
With this set the lens breaks out of the frame
It’s lensed, but the standard of the lens is unknown and the frame fitting the lens might not be good enough
Many sales spam their description with paintball, airsoft etc but aren’t designed or tested to the correct standards.
The lens, frame and all fittings must be able to take multiple hits and remain safe in place over your eyes and face
What's wrong with the I4's you have? only trying on different masks will reveal which are best for you so if you can get to a retail shop or event with traders there that's your best bet, asking on places like this is a waste of time as everyone has an opinion and no one but you knows how big your head is or how big your glasses are or what will fit. What works for me may not work for you but i wear E Vents, but my advice would be, if the I4's you already have work for you, stick with them.
