It all depends on what you want. Do you want all the bells and whistles? Does having GPS on your detector tickle your pickle? Most midrange machines like an AT pro will do just about all you need, so will a fisher f5 but for those who have used nothing but lower end machines you can not say that it will perform just as good, pick u same amount of items etc as an AT pro, an F75, a ctx 3030, a deus or a nokta fors gold.
I've had morons walk up to me and act as though their WalMart $99 bounty hunter is as good as my Garrett AT pro..tell me don't bother to detect here because they covered the place with theirs, as he told me my machine was cheap, hell my grey ghost headphones cost more than his machine, my stainless steel shovel that I make cost more..does that mean its better than his, in this case hell yes, i just laughed at him and went on my way and collected the items he couldn't find.
Basically im saying until you have tried more than just a low end machine you really have nothing to base your comparison on. I've had several machines and im down to 4 but I mainly use my Nokta Fors gold because it has all I need and gets the job done very well, I haven't learned it completely because it has nuances im not yet accustomed to yet. I think its all about learning your machine but making sure you are happy with what it can do and also being honest with yourself do you need GPS, do you need a cup holder, do you need it to talk to you etc or is that for showing off.
