The first 5 chapters can be progressed through at quite a reasonable rate and for me were definitely the most enjoyable parts of the pack. Once you reach the final chapter, material costs suddenly shoot up and it becomes a bit of a grind to reach the end - you'll either need to keep upgrading all your existing infrastructure, or do what I did and just AFK a lot...
Generally, the gameplay is very enjoyable, although my only real gripe is the MI overclocking/efficiency system which I have to say I'm not a huge fan of when it is the only way to speed up machines. Essentially, there is only one version of each machine (unlike GT where you can craft LV/MV/HV macerators, for example), and these can be sped up by repeatedly crafting the same recipe, which increases their efficiency, which overclocks the machine allowing it to draw more power and run faster. You can increase the maximum overclocking of a machine by adding upgrades, however this only increases the maximum speed that can be reached, and there is (as far as I can tell) no way to increase the base process speed. So, if you have a recipe that takes 2 minutes, you can throw as many overclockers as you want at it, but the first craft will still take 2 minutes to complete, and if you want it to run at say, 2s / craft, you'd have to leave it running for quite a while to reach that efficiency, and if for whatever reason it cannot continue crafting (run out of power / no input item / output full), you lose all that efficiency and you're back to square one, which can be frustrating. This system pushes you to have one machine dedicated for every recipe, and you'll want to have essentially every component being generated passively, as opposed to doing any on demand crafting. This has the knock on consequence of severely nerfing the effectiveness of AE2 autocrafting with machines, so you do have to approach this pack differently to a lot of other modpacks and can't rely on AE2 as heavily.
