The Geekvape Aegis or the Geekvape Aegis Legend? Either or, both are excellent devices, the Aegis houses a single battery, where the Legend is 2 batteries. You’ll get more run time with the Legend at the expense of a larger device.
I have never seen the Pico Dual until you mentioned it and I performed a search. Don’t know if how that battery housing is situated whether it would hinder using a larger tank. What tank do you own?
My only concerns with devices that do not have replaceable batteries is once that battery’s life cycle comes to an end, the whole device has to be replaced. You also cannot swap the battery for one that is fully charged. Many carry extra batteries with them when on the go for this purpose. ALWAYS use a proper battery case when carrying batteries!!
