Differences between Sangoma Cloud based PBX and on-premise PBX:

Cloud based Sangoma PBX (you rent the PBX):

If you want as little equipment as possible in your office and as simple a setup and phone bill as possible and you are not looking for the lowest possible phone rates / phone bill, but just a nice low phone bill with the same amount every month, the Cloud based PBX could be for you.

If you generally like and have a lot of your stuff if the Cloud, the Cloud solution might be an obvious choice for you as you are used to the advantages (and disadvantages) of living in the Cloud.

Stuff like updates, security, backup and disaster recovery is taken care of automatically for you in the Cloud, whereas you can have the occasional "yearly" outage outside your control.

The cost of Sangoma's Cloud solution is $24.95 per month per hard extension (dial tone), which includes 4500 minutes of in- and outbound calls, and $8.95 per additional "soft extension". The only other cost than this is $1 per month per phone number, $10 per phone number that needs to be ported over to Sangoma and the additional cost of any PBX add-ons if needed (rare).

If your have a very high call volume the Cloud solution might be for you due to it's fairly inexpensive "unlimited" call plan as per above. If you go beyond the allocated 4500 minutes per month Sangoma is reasonable about it until you are consistently going beyond the plan and they will then simply ask you to i.e. add another trunk at $24.95 per month.

A very few number of add-ons like XactView is NOT available in the Cloud solution.

Scalability is easy with the Sangoma Cloud solution as it can grow with you "indefinitely".

On-premise Sangoma PBX (you own your PBX):

If getting your monthly phone bill as low as possible with any means possible, owning your own PBX is your best bet as you can choose any VoIP phone provider you wish. This is a great way of making sure that you always use a nice low VoIP provider at i.e. $0.01 per minute for domestic calls.

If you call volume is not especially high incoming and outgoing the on-premise solution is probably for you due to the low calling rates per minute. If your call volume is high there is no difference between the Cloud based or on-premise solutions.

If you like having control over and owning your own equipment the on-premise solution is ideal for you as you own and operate every single piece of equipment concerning your phone system.

The general monthly phone bill when you own your own PBX depends a lot on your habits. You can a cost calculator to get an idea of your monthly cost. Generally speaking, owning your own PBX gives you a monthly bill around 20% ​lower than the Cloud solution. You don't get billed for number of extensions on your own PBX, so you can have as many as you like without extra charges. 

Very high call volumes can also be just fine with the on-premise PBX as there are plenty of VoIP vendors out there with "unlimited" call plans. But generally speaking the Cloud solution's "unlimited" plan is very good where as the "unlimited" plan (via SIPstation, a Sangoma company) "only" has 3000 minutes per month (versus 4500 minutes in the Cloud).

All add-ons are available on the on-premise version of the Sangoma PBX including XactView.

Scalability is also fairly easy with the Sangoma on-premise solution(s), but it sometimes will require a new and bigger PBX.
