In our opinion, there is no general strengths and weaknesses of specific valuation methods. Everything depends on the particular case and circumstances.

It should be taken into account the object and purpose of valuation, type, and characteristics of the transactions, the exploitation fields of intangible assets, the role of intangible assets in the process of generating added value, a portfolio of other physical and non-physical assets, business strategies, etc.

The particular method of valuation will, therefore, be suitable for use, or will not be appropriate for use.

If two or three valuation methods will prove to be suitable for use, there is no justification for the choice of one and reject the other. 

Especially if the use of several methods will assess the value of from the different points of view (e.g., due to another theoretical basis of valuation methods and a possibility to collect needed data). This, in turn, can reduce the risk of committing a material error.

Limiting the use of one method of valuation deprives the chance to evaluate further the reliability of the obtained results. The second method could, e.g., serve as an additional verification result of the valuation obtained by a method which has been recognized as a primary way.

Recognition that accepted methods are equally reliable should allow establishing recommendations based on range defined by the results from the used methods. In the particular case, it will lead us to the median of the distribution (assuming equal probability of occurrence of each value of the designated numeric range).

In the event of application of stochastic models and simulation analysis used as a tool by different valuation methods, the result of each of the methods can be set at the median of the distribution generated using these methods. In this case, coefficients of variability of distributions could be used to assess the relative reliability of the results obtained with these methods. Indicators of this kind reflect the level of uncertainty (risk measure). Information characterizing the conditions set for the adoption of key variables assumptions of a valuation model.

In practice, in many cases, the valuation of intangible assets using different valuation methods reveal various aspects of the assessment of the economic value associated with the possession or use of these assets.

It should be utilized more than one method of valuation to reduce the risk of committing a material error (that is, however, usually with a higher valuation costs).

The use of several valuation methods is natural and practiced when the assessment is carried out in the context of the transaction. Especially when you need to fix a numerical interval in which unrelated parties are seeking the transaction price and formulate crucial arguments negotiation, which is clearly in line with the principle of ALP.
