2 major things for this argument, especially in a commercial sense is...
1. Consistency
2. Availability
Main issue in say chain stores like gloria jeans, starbucks......whatever even in most restaurants and cafes, is that insufficient knowledge about coffee means people grind too much and leave it there. It takes a very watchful and tireless manager to tell a casual staff member over and over to do something they care nothing about and that is one point for doser-less grinders
Next issue is speed, anyone having worked in a high intensity situation will definitely realise that speed is the major factor in the argument, with a doser model you are very rarely out of ground coffee, in busy times its all getting used anyway! So that rules out freshness, and once the chamber is full creates simple consistency. Doser-less models would really really have to be on their game to keep up with a barista eg ball park figure of my own performance, hitting a double basket every 7 seconds! so that means it has to grind at least 20g of coffee in about 5 seconds! Pretty fast, not impossible but does it stress the beans too much or is it a very high quality low stress conical setup..... very important with all espresso grinders is that they are conical, if you want quality and burrs to love the bean then go conical!!!! DO IT!!!
Grinders are a vital part as Mal said, they should be in espresso situations micro-metrical stepless adjustment meaning infinite adjustment meaning perfect control. Both would come with this feature, however most commercial grade doser-less models are designed eg gloria jeans and starbucks...grinders coffee etc are designed to grind straight into say a 500g bag for a customer.. not every 5seconds neatly into a PF and thus are usually just step adjustment.
Our company is working on moving all 9 of our cafes across to doser-less, im skeptical but i can see the potential if grinder manufacturers are up to it, as i havent seen many espresso oriented versions. Nor ever worked with any.
Suffice to say with good quality staff and high volume cafes then doser is going to be the best choice.
Home use can fluctuate either way depening on cost and mess, the doser or not really makes little difference, just make sure u get stepless adjustment, conical burrs (not necessary but preferable)
Chain stores, stepless is the way of the future. Have you every tried teaching a barista who has been making average coffee for 6 years how to free dose consistently? or a 16 year old who doesnt give a shit?? not the easiest task, not impossible but replicate that scenario 10 times per shop for a new shop every month...... pain pain pain hahaha
Comes down to the needs of the buyer and the budget
PS go conical!!
