I too found some of the perceived limitations a bit frustrating to start with. However, you have to realise what the device is and isn't at this price point. For the price, to me it's a simple choice of functionality vs tone. You can get alternatives with more functionality, but tone is more important to me.
What I have also recognised is that you can be a bit creative with how you use the device; yes it would be nice to add a couple of extra devices in the chain, but it's very, very rare I need all FX switched on at the same time so you just set up another patch with a different configuration - that's still only one button to activate (the same as activating another stomp). If you need 180 seconds of looper time, maybe a dedicated looper with the PodGo would be a good compromise, or go for the Mooer and sacrifice a bit of tone.
