Is FTTN worth it?

Where I live, I basically have 2 ISP choices: the national cable company and the national DSL company (i.e. the national telco). Currently I'm using cable, but since they recently started usage based billing, I've been looking at switching.

The national DSL company offers both DSL and fiber, but the fiber package comes with the following fine print: "‡ Fibre optics may service all or part of your network connection, depending on location." That said, given the same advertised connection speeds (15-25 Mbps), would the FTTN internet package be worth a $10-$20 price premium over the regular DSL internet package?

 

Hard to say not knowing how is this set up.
FTTN basically rules out any form of DSL, so it's a DSL company offering DSL & cable Internet, isn't it?
You don't know what speed DSL would achieve in your location. If you're rather close to DSLAM your speed is going to be higher than if you're far from it.

That makes it hard to answer the question price-wise. Additional $20 sound like a lot. What would be the speed and price of DSL connection and what would be the speed and price of fiber?

 

There's actually 4 packages here - 15/25 Mbps DSL and 15/25 Mbps fiber. If I understood the pricing chart correctly (and there's a good chance I didn't because they include time-limited promotional pricing, cellphone style multi-year contract discounts, and multiple service bundle discounts), the 15 fiber costs $10 more than the 15 DSL and the 25 fiber costs $20 more than the 25 DSL.

 

Doesn't seem to be worth it. As I wrote it's possible that you might not get the full speed on DSL is you're far from DSLAM (that would affect the faster package more)- that's something that won't happen on fiber, but price difference is too big to justify buying the latter- at least in my opinion.

EDIT: BTW I assume that by DSL you mean ADSL- in such a case max speed that can be achieved with ADSL2+ is 24mbps so 25mbps isn't even possible- they must have rounded the number a bit

 

It's not so much the cable type or delivery mechanism these days that rules the performance of your internet connection.

It is the kind of traffic shaping or blocking that your ISP is doing.
