Great question!
While there is no golden rule of thumb, but I would say that if the log file does not grow by leaps & bounds or if you have limited storage, you may want to stick with growth value in MB.
Here's the reason:
Growth in MB is a constant, linear growth. So, 1GB growth for a log file of 10GB will cause the log file to grow from 10GB to 11 to 12GB and so on.
A percentage growth is the percentage with respect to the size of the log file at time of increment. Therefore this will not be a linear growth. For a 10% growth increment, a 10GB log file will grow to 11, 12.1, 13.31 GB and so on.
When % is specified, the growth increment size is the specified percentage of the size of the file at the time the increment occurs. The size specified is rounded to the nearest 64 KB.
