Points where to be careful

The 6 can sometimes see the 8 as being too authoritarian, aggressive, intimidating, overprotective, conflictual and excessive.
The 8 can sometimes see the 6 as being too indecisive, irrational, suspicious and paranoid.
If the 6 is counterphobic, the 8 can also see him as aggressive, rebellious and confrontational.
The 8 can be impatient with the fears of 6 and trivialize them. If the 8 becomes too domineering and intimidating, the 6 counterphobic can revolt to prove that he is neither weak nor dependent. If the 6 is phobic, he will react differently and adopt a passive-aggressive attitude to avoid confrontation.
