Not sure if others know but, like some companies have different brands for different markets Janibel, Akord and Diaper Dekor are same product and or company like one is marketed towards babies and one towards healthcare.
When I first became Incont I tried many different ones and settled on the Dekor classic(though the foot pedals in my situation sucks) and for sz Med medical diapers it works well (I will say the avg to Mid-grade medical diapers generally speaking are smaller than the higher capacity ones in all sizes) though I wanted to upgrade to the the Janibel 400DS 13 gallon model which few on here recommend I still have a hard time with not only the price of it($110+) but also liners are up there & feel where it's marketed towards disabled community like other things they jack the price up. So a Dekor Classic 7 Gal is like $35+, Dekor Plus/Janibel/Akord 330 11gal $49+, Janibel 400DS 13 Gal ($110-160+). Also food for thought a Janibel 400bw 11g & 450bw 17gal trash cans that uses liners system but doesn't have top for diapers sells for $65+(so like I mentioned they jack price up for.the 13 gal diaper pail). Per Janibel the difference between 10 & 13gal is 15 Lg diapers per load which assuming are hospital or store grade ones, though size wise the 400DS is bigger overall I personally don't see where 2 Gal will make that big of a difference or a $60+ difference (I personally use 3-4gal trash bags when out and for smelly ones and they hold one maybe 2 diapers) also another difference in the Plus/330 like you can get slightly more discreet bag/liners where bigger ones are clear only and little to no off brand options.
I will add the Dekor, Akord, Janibel has the widest tops for liner baged systems. And the reason I originally chose it and why it's something I still ponder. I will say I did like the Diaper Champ for smaller diapers as it sealed well and it used 13gal.trash bags but bigger diapers get stuck.
