surgery for back and neck pain

I was wondering, if you can kindly help me decide on what type
of surgery I should go for.
If you can give some advise based on my symptoms, I will appreciate it.
I got the mid sagittal spinal canal diameter -in mm.
They are as follows: C2: 14, C3-C3:13, C3:12.3, C3-C4:13, C4:12,
C4-C5: 13; C5:13; C5-C6: 12.5; C6:12.3; C6-C7:9 ; C7:12

My C6-C7 level  shows focal left sided posterior herniation
compressing the thecal sac and mildly indenting on the cord. There is
also unco vertebral osteophytes causing left neural foramnal stenosis
with indentation of the exiting c7 nerve root.

C5-C6 shows mild left paracentral bulge.

I am not sure, if I should go for "Artificial Disk Replacement" even
though the doctor has suggested it. microdisketomy without artificial
replacement seems
to be a better option, though it will restrict my movement of neck
because of fusion. Please advise.
